Examples of org.jboss.cache.CacheSPI

org.jboss.cache.CacheSPI
A more detailed interface to {@link Cache}, which is used when writing plugins for or extending JBoss Cache. A reference to this interface should only be obtained when it is passed in to your code, for example when you write an {@link org.jboss.cache.interceptors.base.CommandInterceptor} or {@link CacheLoader}.
You should NEVER attempt to directly cast a {@link Cache} instance to this interface. In future, the implementation may not allow it.
This interface contains overridden method signatures of some methods from {@link Cache}, overridden to ensure return types of {@link Node} are replaced with {@link NodeSPI}.
